—or, indeed, anything else that would add unnecessary weight.
—确实,任何其他装置都会给这架无人机增加不必要的重量~Wr,2[iiay3
The touchdown meant the Zephyr S had set a new flight-endurance record for a drone, of 25 days, 23 hours and 57 minutes.
此次着陆意味着Zephyr S创下了无人机飞行耐力的新纪录—25天23小时57分钟2Wt_f._)i#OSpRnbwI
The point of doing so was to show that solar-powered aircraft of this sort
此次飞行的意义在于展现这种太阳能航空器
